Recently,researches about impulsiveness are more and more active,especially in the fields of psychology,psychiatry,behavioral medicine and psychopharmacology.But there is no widely accepted definition and measurement methods.This review briefly described the concept of impulsiveness and different methods to measure impulsiveness.We also discussed the advantages and disadvantages of each measurement method.

With the increasing perfection and improvement of microsurgery technique in modern ophthalmology, especially the popularization of micro-incision cataract extraction and the rise of femtosecond-laser-assisted cataract extraction, the cataract extraction and intraocular lens implantation is gradually transformed from vision rehabilitation surgery into refractive surgery and people also pursue better postoperative visual experiences. However, the preoperative and postoperative corneal astigmatism is always the main factor affecting the postoperative visual effect. ln recent years, the development of design and materials of the intraocular lens ( lOL) provided necessary basic conditions for clinical application of the Toric lOL. The Toric lOL is primarily characterized by effective correction of cataract patients′postoperative corneal astigmatism, which results in the enhancement of patients′postoperative visual function. ln this paper, the design, classification and clinical application of Toric lOL were analyzed, and current problems and prospect were discussed.

Objective To investigate the effect of nalmefene on sufentanil and propofol anesthesia for abortion and its impact on BIS. Methods One hundred and twenty patients undergoing abortion patients were randomly divided into group A, B, C, and D (n = 30 each). Patients in group A and B received 0.2 μg/kg or 0.3 μg/kg sufentanil, respectively, followed with 1.5 mg/kg propofol for induction of anesthesia post-pretreatment with 0.2 μg/kg nalmefene. Patients in group C and D received induction of anesthesia as patients in group A and B. According to the BIS and fluctuation of hemodynamic , the amount of propofol was adjusted. If necessary, additional single intravenous injection of 0.5 mg/kg propofol. The mean arterial pressure (MAP), heart rate (HR), pulse oxygen saturation (SpO2) and respiratory rate (RR) in patient before injection (T1), the eyelash reflex (T2), dilatation (T3), curettage (T4) and surgery awake (T5) were detected. The additional amount of propofol , operation time , recovery time of surgery , the steward score of orientation recovery after 1min of surgery , body movement reaction , cough , respiratory depression , postoperative visual analog digital score (VAS) 15 min later were also recorded in each group. Results Compared with group A, propofol could reduce the intraoperative body movement reaction rate , with lower postoperative VAS in group B and group D (P <0.05, respectively), with no significant difference between group C and group A (P > 0.05). The rapid recovery, surgery within 1 min orientation recovery were higher in group B, C, D compared with group A (P <0.05). However, orientation recovery score in group D was higher than that in group B (P < 0.05); The respiratory depression and choking were higher in group A and B than those in group C , D (P < 0.05, respectively). Conclusion The doses of 0.2 μg/kg nalmefene can effectively antagonize the respiratory depression , delay recovery and other adverse reactions in painless which induced by sufentanil , and the dose of nalmefene in this study failed to enhance the effect of analgesic and change the BIS values.

Transforming growth factor-β is an important cytokine with various bioactivities, including embryonic development, wound healing, chemotaxis and cell cycle regulation. Epithelial-mesenchymal transition (EMT) is the main pathway of tumor cell to obtain the ability of invasion and metastasis. The TGF-β is the key factor known to induce EMT in cancer cells and plays an important role in the process. In recent years, some progress has been obtained. Some TGF-β inhibitors have approved in the market or in clinical trials. TGF-β inhibitors can play an important role on the treatment of tumors, glaucoma, liver and kidney fibrosis disease and scar repair. Novel TGF-β inhibitors reported in recent years were reviewed in this article.

Objective To study the application value of high frequency ultrasound to the diagnosis of early rheumatoid arthri‐tis .Methods 40 cases were selected ,who were diagnosed with early rheumatoid arthritis ,as the RA group ,another 40 healthy per‐sons were selected as the normal control group .Objects in the 2 groups were examined with high frequency ultrasound and X‐ray . Comparison of the examination results was made ,at the same time ,the results of suprapatellar bursa effusion ,synovial hyperplasia and bone erosion of the positive detection rate in group RA from the analysis of high‐frequency ultrasound and X‐ray examination were also compared .In addition ,the relativity between the related index and ESR index and CRP index in group RA was also ana‐lysed .Results The suprapatellar bursa effusion ,synovial hyperplasia ,bone erosion of color flow rate and bone erosion of the posi‐tive detection rate were higher than those in normal control group(P<0 .05);Compared with the control group ,the artery resist‐ance index was less ,the femoral condyle and lateral condylar cartilage thickness of RA group increased more(P<0 .05) .High fre‐quency ultrasound positive detection rate suprapatellar bursa effusion ,synovial hyperplasia ,bone erosion in patients of group RA were higher than those of X‐ray(P<0 .05) .The knee joint suprapatellar bursa effusion ,synovial hyperplasia of synovial membrane thickenss ,the thickness of the color blood flow grade and CRP ,ESR of patients in RA group were correlated(P<0 .01) .Conclusion High frequency ultrasound can respond to the situation of early rheumatoid arthritis patients ,and the lesion detection rates are higher ,there is a certain correlation between ultrasonographic indexes and CRP ,ESR .

OBJECTIVE To analyze the reasons of misdiagnosis and surgical complications of primary lymphoma of thyroid gland(PLT). METHODS The clinical data of 10 patients with PLT in our hospital from 1992 to 2006 were retrospectively analyzed. RESULTS All of 10 patients were misdiagnosed,the major surgical complication was hoarseness. CONCLUSION The misdiagnosis of PLT is often encountered. Mastering the clinical features,using fine-needle biopsy,rapid biopsy combining immunocytochemical method can diagnose the primary lymphoma of thyroid gland.
